
Syntax
U16 PASCAL _ECAT_Security_Write_UserPassword (U16 CardNo, U32 *UserPassword)

Purpose
Write in the user password into the verification IC.
Note:
1. Before write in the user password, users should use the API function (in setion 6.1 and 6.2) to initialize
the EtherCAT master. Also, use the API function in 29.5 to confirm the password beforehand.
2. The new password will be valid immediately. Users will need to use API
"_ECAT_Security_Check_UserPassword" (section 29.5) to log in again to use other APIs in this
chapter. Once the password is changed, please do remember the new password as Delta can no
